It combines the movement and timing of traditional block games with the word juggling of scrabble. Touch-slide the ever falling lettertiles around the screen to make words, and not just while they fall but when theyre stacking up.

Unlike other games you have full control over word making with your tiles.

When youve made a word, you choose when youre ready for it to be counted; allowing you to increase its length or make a combo. A simple tap and your word vanishes while the points roll in, the tiles above falling into the gap.

But beware, if you let a stack of tiles get too tall and hit the Danger Zone at the top of the screen then its game over!

Control is simple and intuitive, and the visuals elegant.

Letrix has an extensive US and UK English dictionary at its heart, covering words of three to seven letters. There are 20 levels to test yourself against, with tiles dropping in varied patterns, increasing in speed and number as you progress.

Score-multipliers for combos and longer words reward clever play.

There are two play modes in this edition, Rolling Play: seeing how far through the game you can get, and Stand Alone Play where you can dip in and out of previous levels. Specific achievements are also provided for players to try and reach.

High scores for Rolling Play and individual levels are all recorded, so theres plenty of opportunity to improve your personal bests.

As no level plays the same twice, each time you play its a new challenge!
